The epidemics of donations: logistic growth and power-laws. [PDF]

open access: yesPLoS ONE, 2008
This paper demonstrates that collective social dynamics resulting from individual donations can be well described by an epidemic model. It captures the herding behavior in donations as a non-local interaction between individual via a time-dependent mean ...

Analysis of Growth Characteristics of Kimchi Cabbage Using Drone-Based Cabbage Surface Model Image

open access: yesAgriculture, 2022
Cultivation soil is the basis for cabbage growth, and it is important to assess not only to provide information on how it affects the growth of vegetable crops but also for cultivation management.

Cost-benefit modelling for reliability growth

open access: yes, 2003
Decisions during the reliability growth development process of engineering equipment involve trade-offs between cost and risk. However slight, there exists a chance an item of equipment will not function as planned during its specified life. Consequently

Revisiting the Logistic Growth with Random Disturbances [PDF]

open access: yesMathematica Applicanda, 2019
Summary: The logistic growth population model still can help explain ecological phenomena. We consider a simple 1-dimensional model of savanna introduced by \textit{P. D'Odorico} et al. [``A probabilistic analysis of fire-induced tree-grass coexistence in savannas'', Amer. Natur. 167, No. 3, E79--E87 (2006; \url{doi:10.1086/500617})] which is in fact a

Mycobacterial cell division arrest and smooth‐to‐rough envelope transition using CRISPRi‐mediated genetic repression systems

open access: yesFEBS Open Bio, EarlyView.
CRISPRI‐mediated gene silencing and phenotypic exploration in nontuberculous mycobacteria. In this Research Protocol, we describe approaches to control, monitor, and quantitatively assess CRISPRI‐mediated gene silencing in M. smegmatis and M. abscessus model organisms.

Systemic dysregulation of apolipoproteins in amyotrophic lateral sclerosis serum

open access: yesFEBS Open Bio, EarlyView.
Amyotrophic lateral sclerosis (ALS) is a fatal disease that damages motor neurons. This study found that people with ALS show significant changes in blood fats and the proteins that carry them. Several apolipoproteins were higher, lipid balances were altered, and normal protein–lipid relationships were disrupted.

Metastases Growth Patterns in vivo—A Unique Test Case of a Metastatic Colorectal Cancer Patient

open access: yesFrontiers in Applied Mathematics and Statistics, 2019
Colorectal cancer (CRC) is one of the most common causes of cancer-related mortality worldwide. Most cases of deaths result from metastases, assumed to be shed, in many cases, before disease detection.

A New Logistic Model for Bacterial Growth

open access: yesJournal of the Food Hygienic Society of Japan (Shokuhin Eiseigaku Zasshi), 2003
A new logistic model for bacterial growth was developed in this study. The model is based on a logistic model, which is often applied for biological and ecological population kinetics. The new model is described by a differential equation and contains an additional term for suppression of the growth rate during the lag phase, compared with the original
